This Controller Is Capable Of Driving Two Stepper Motors Over 8 Conductor Cable (typically CAT5 cable).  Current Control Is Necessary To Protect The Stepper Motors.  The Display Shows Stepper Motor Position In Terms Of Step Number And Current Used For The Latest Stepper Motor Movement.  This Unit Is Extremely Accurate And Re-Settable.  It Utilizes Replaceable H-Driver Modules Which Are Current And Temp Protected.  This new model provides full control of a balanced tuner (addition of three relay control outputs, 2A Source Current).  The relay control outputs are associated to the memory positions.  Therefore, once programmed, the operator does not have to worry about vacuum relay positions within the ATU!  Switching is accomplished automatically.  See full Description and Manual download at steppertune.com  Gary, K7EMF
 

Relays Within The Balanced ATU May Be Controlled Also With StepperTune-BT.  During Normal Operation, If The Auto-Tune Button Is Depressed, StepperTune-BT Will Go Into The Relay Control Mode Represented Below.  Each Memory Position (1 thru 8) Is Associated With Switch Positions ( H Imp-C1-C2-Memory Position)Pictured Below.  While In This Mode, Each Switch Output Is Displayed In Real Time So That The Operator May Use This Mode To Setup The ATU For Each Band.  It Is Suggested That At Least One Memory Be Setup For Each Band Of Operation (Example: M1=1945Khz, M2=3885Khz, M3=7290Khz).  Each Memory Related Switch Position Is  Memorized Into Non-Volatile Memory So that In Operation, The Switch Modes Are Automatically Used For Each Memory Position! 

During Normal Operation, If The Operator "Touches Up Tuning" Within The Memory Band, The Switch Positions Are Not Changed.  The Only Operation That Will Change The Switch Outputs Is If A Different Memory Position Is Initiated.  

To Exit The Switch Setup Mode, Simply Depress The Auto-Tune Button And StepperTune-BT Is Back In Normal Stepper Mode. 

Preferred Stepper Motor For ATU:  Nema 23 rated at 12V and .5 to 1 Amp.
